1.4 Islands Snorkeling Tour by Longtail Boat

★★★★★★★★★★4.1 · 297 reviews · 6 hours · from $31Our pick

Set out from Koh Lanta Yai by longtail boat for four island stops, with snorkeling at Ko Chueak, Ko Ma, and possibly Ko Waen, plus a swim through Koh Muk’s Emerald Cave. Lunch, fruit, drinks, gear, hotel transfers, and an English or Thai guide are included.

“Not a bad day out - the long boat was fine, but it is an hour there and back. It was very crowded, the boat was full and each location we stopped at was packed with people. The snorkelling was fine but not amazing. If you think of this as some swimming, beaches and lunch, you’ll probably like it. But it’s far from quiet.”

“Liian kiire joka paikassa ja liikaa ihmisiä. Opas epäselvästi kertoi ajan paikoissa. Snorglaus paikkassa ei mitään katsottavaa ja ihmisiä todellakin liian paljon. Vieri vieressä kymmeniä ihmisiä pienellä alueelle . Ja vielä opas unohti laskea porukat kun lähdettiin luola uinilta ja yksi asiakas jäi matkasta. kuski huomasi virheen ja äkkikäännös takaisin luolille. Mies löytyi luolien edestä ja onneksi oli pelastusliivit päällä, mutta paikalla oli enään kaksi pitkähäntävenettä. Todella huonoa asiakaspalvelua.”
